My fourth grader just transferred this year from a regular school to a self-contained classroom program for highly gifted in a different school and district. It's REALLY stressful, although she's more than capable of handling the level of work in the class. It's a huge change to go from having everything be easy to having to put in some effort, and not necessarily being the smartest kid in the room all the time. And she's old enough to tell us that she doesn't like it, and why! Hopefully, it's not too late for her to readjust. I don't know how helpful this is to you, except to say that we're going through the same thing, and I think it's better to experience it at 6 than at 9.
